For starters, I think the developers should explain their idea on how the MA actually be useful. Apart from being a white elephant that consumes relics while providing tiny temporary perks, there truly is nothing interesting about the MA.
I would say let the MA generate spells automatically at a lower level, to get a more stronger spell to be generated some relics need to be added to enhance it. Not keep inserting to get a lousy spell
That way, you can keep getting the boosts intended andat the same time encourage some battles. even thought the battle system is still not so good to work with erroneous turn table, almost always lower quarter damage done by player units while the AI almost certainly does near max damage at every hit.
